Like the hands video you import from your computer and not anything you do in post color grading
Oh! You got me wrong. I am just asking about the keys with that nice look. Not the LEDs which glow when you hit a note and I would like you to make a tutorial in which you don't use your actual LEDs and add light in the SeeMusic software.
That video uses actual LEDs on the piano. There isn't any way to do that in post-production.
SeeMusic does offer the best possible solution to make a video with lights without having an actual LED strip using the "Add Light to Video" feature in Light Settings.
